DISCUSSION
Tonight...the strong upper level low that has brought rain and some snow to the area will continue to linger in the area tonight.
Still looks like a good shot of snow will wrap up on the north side of this low into the Central Sierra mostly south of Interstate 80. Snow levels should also drop this evening and overnight to around 6000 feet with additoinal accumulations of 12 to 18 inches still possible. Been a hard snow forecast as the first ones are with melting snow and warm ground. As far as rain in the valley, system looks to continue to wrap around light and sometimes moderate rain this evening with amounts generally up to around a half inch additional.

Wednesday...the upper low does pull off to the east. This will put most of NorCal in dry northerly flow. Temperatures remain cool genreally in the lower 60s.

Thrusday through Saturday we will be in a short wave ridge situation which will bring us some pretty mild fall weather in the 70s.

Sunday...pretty good agreement in models that a very progessive upper wave will push into the PacNW. Winds aloft look to be somewhat hefty which will bring some gusty winds to higher terrain but with fire weather not an issue right now impacts should be little to none. May also be some gusty winds, especially northern Sacramento Valley Sunday but nothing looking like a wind advisory at this point but will see how this developes.

Monday...above mentioned PacNW system pulls into across the norther U.S. and does open up some slight inside slider northerly flow. This also isn't looking too impactful but if energy dives further south could result in stronger north winds...but even with that seems like it would be below adivsory level. WMR
